  1. What is an Electrical Installation Certificate (EIC)?

    • AA test equipment brand
    • BA certification confirming a new installation complies with BS 7671
    • CAn insurance document
    • DA maintenance log

    Answer: An EIC certifies that initial verification has been completed and installation meets BS 7671.

  2. What must be included on an EIC?

    • AOnly the installer's name
    • BDesigner, installer, inspector names; test results; description of work; and compliance declaration
    • CJust a date
    • DEquipment prices

    Answer: EICs must contain detailed certification of design, installation, testing, and compliance.

  3. What is a Minor Electrical Installation Works Certificate (MEIWC)?

    • AA full installation certificate
    • BCertification for non-notifiable minor electrical work, not requiring full EIC
    • CAn equipment test certificate
    • DNot used

    Answer: MEIWCs certify minor works such as single circuit modifications.

  4. What is an Electrical Installation Condition Report (EICR)?

    • AA design document
    • BThe report from periodic inspection of existing installations, detailing defects and recommendations
    • CAn annual maintenance plan
    • DA warranty document

    Answer: EICRs document the condition of existing electrical systems and identify any defects.

  5. What are the typical codes used in EICRs to classify defects?

    • AA, B, C only
    • BC1 (urgent), C2 (requires urgent attention), C3 (requires attention), and observations
    • CJust Pass/Fail
    • DColor coding only

    Answer: EICR codes: C1 (dangerous), C2 (potentially dangerous), C3 (non-compliant), and observations.

  6. Who can issue a valid EIC?

    • AAnyone
    • BA competent person or qualified electrician registered with a Part P scheme
    • CInsurance company only
    • DBuilding surveyor only

    Answer: Valid EICs are issued by competent persons, typically registered electricians with schemes like NICEIC.

  7. What information must be on a Schedule of Test Results (SOR)?

    • AJust a project list
    • BAll measured test values, dates, instrument used, and acceptance criteria for each test
    • CEquipment serial numbers only
    • DJust signatures

    Answer: SOR documents all electrical test measurements and must show how results comply with BS 7671.

  8. What is the relationship between an EIC and Part P Building Regulations?

    • ANo relationship
    • BEIC serves as evidence of Part P compliance for electrical work
    • CPart P only applies to plumbing
    • DEIC is not related to building codes

    Answer: EICs provide evidence that electrical work has been done safely and complies with Building Regulations Part P.

  9. How long should electrical installation documentation be retained?

    • A1 year only
    • BMinimum 7 years for future reference and legal purposes
    • C3 years maximum
    • DNo requirement

    Answer: Electrical documentation should be retained for at least 7 years.

  10. What must be documented for each protective device?

    • AJust the type
    • BRating, function, breaking capacity, and location
    • COnly the manufacturer
    • DNothing specific

    Answer: Protective devices must be documented with type, rating, breaking capacity, and clear labeling.

  11. What is the purpose of a cable schedule in electrical documentation?

    • ACost tracking only
    • BClear identification of all circuits, cable sizing, routes, and protection details
    • CEquipment inventory
    • DNo purpose

    Answer: Cable schedules document all circuits with sizes, routes, and protection for maintenance and safety.

  12. What must be documented regarding circuit loads?

    • AJust the highest load
    • BEstimated load in amps for each circuit, allowing verification of cable sizing
    • CLoad is not documented
    • DOnly three-phase loads

    Answer: Circuit loads must be documented to verify cables are correctly sized.
